In
1992, the California legislature added a risk reduction component, the
Facility Air Toxic Contaminant Risk Audit and Reduction Plan (or SB 1731),
which required the District to specify a significant risk level, above which
risk reduction would be required. In Rule 1402, the District Board establishes action risk levels
as follows:
- Cancer risk
> 25 in one million
- Cancer Burden > 0.5
- Hazard Index > 3.0
Facilities above the action risk level must reduce their risks below the
action risk levels as complying schedules specified below:
- 180 days to submit a Risk Reduction Plan
- 3 months for the District to approve the Plan
- 3 years to implement the Plan
